The present disclosure relates to a communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. In particular, the present invention relates to a wireless communication system and, more particularly, to a method and device for transmitting or receiving a synchronization signal, a physical broadcast channel, a control signal, and a data signal in a system supporting transmission and reception through a narrowband channel of about 180 kHz. Specifically, the present invention defines an in-band mode operation of an LTE-lite terminal in order to avoid collision with a conventional LTE terminal, and provides a method for using a reference signal, a method for periodically puncturing a specific slot, and so on. |
